Title: Optical signal identification system
Inventor: NISHIO MAKOTO
IPC: H04J14/02
Filed: 1987-06-26
Abstract: PURPOSE:To attain low operating speed for a circuit whose wavelength is to be identified and to simplify the circuit constitution by adding an input data signal to an identification signal having a lower frequency than a predetermined input data signal band for each wavelength of light and converting the result into an optical signal. CONSTITUTION:An identification signal 1 of a sufficiently lower frequency f1 than the frequency of data signal band is added to an input data signal 1 by an adder 110 and an identification signal of a low frequency f2 is added to an input signal 2 by an adder 111 (f2not equal to f1). The output of the adder 110 is converted into an optical signal of wavelength lambda1 by an electrooptic converter 120 and an output of the adder 111 is converted into an optical signal of wavelength lambda2 by an electrooptic converter 121. The optical signals are multiplexed by a wavelength multiplexer 130 and sent to transmission line changeover devices 100, 101 via a wavelength multiplex transmission line 131 and a branching device 140. Since the low frequency identification signal is added to the input data signal in this way. The constitution of the circuit extracting the identification signal is made simple and may be operated at a low speed and low power consumption is attained.

Filed: 1986-07-09
Abstract: PURPOSE:To attain immediate connection even if a call by a handset and an incoming call from a telephone line take place simultaneously by applying the connection between the handset and a base unit according to a prescribed procedure.

Abstract: PURPOSE:To detect the position of a digging machine in a horizontal direction with high accuracy and high sensitivity by detecting the strength of a magnetic field formed by parallel reciprocal wires movable in parallel on the ground by a detector provided within said digging machine. CONSTITUTION:Parallel reciprocal wires 13 are provided on the ground with a distance 2W therebetween. A reciprocal current is flowing in the wires 13. Magnetic field detectors 11, 12 are provided in the upper and lower parts of a digging machine 1, respectively, which detect the magnetic field in a horizontal direction perpendicular to the advancing direction of the digging machine 1.
